Fig. 10 and track Fig. 10;

Figs. 11 to 23. inclusive. are views of details of construction.

llelerring to the drawings. and especially to Fig. 1. we show a lourdrinier machine having a table supporting rolls 1. over which thewire 15 extends and travels. The table is mounted on pedestals or posts2. 3. 4. 5 and (3'. whereof the pedestals 2 and G are at the lelt andright hand ends of the machine respectively. and the pedestals 3 and 4are located at intervals between the ends. A deckcl strap 7 is shownmounted on wheels 8 and 9 having its lower portion 10 resting on theupper stretch of the wire B and its upper portion 1] mounted onstandards 12 and 13. A breast roll 14 is shown at one end of the machinefor supporting one end of the wire and couch rolls 15 and 16 at theother end of the machine.

In accordance with our present invention the table A is moved or shiftedtransversely to its length or it may be said transversely to thedirection of motement of the wire B, at a time when it is desired toremove and replace a wire. Certain elements of the machine have to belifted out of the way to permit this transverse table movement. Otherelements have to be adjusted or changed in various ways as will beparticularly pointed out hereinafter. Suitable provision has to be madefor the support otthe table when it is drawn or moved as described, andarrangement has to be made for putting a new wire in place. and thenpushing the table back to its normal position. adjusting the wire andthe various parts and elementsQso that the machine normal condition isan end elevation of one post 01 the machine. as shown in describedhereinafter.

As an arrangement for permitting the All this will be in Figs, 3 and 1.In this arrangement there are shown 'two sets of beams 18--18 and 1919.the former of which will be called the back channel tracks or beams andthe latter the front channel tracks or beams. These heams are notnormally in the p0sitions shown in Figs. 3 and 4,'n 0t normally beingina Sense a part of the'machine, but

are put,into position preliminary to shifting the table to change thewire. Each of these beams 18-and 19 is preferably'made in the form of apair of channel beams 20 and 21. as shown in Fig. 8, spaced apart byinto the positions'shown, a rear track 18 and a front track 19 for eachpedestal 2, 3, 4, a and 6. The front tracks 19 are longer than the rearones 18, so that the former extend well through the front posts orpedestals 2, 3, 4, etc, and are fitted to the rear oncslS by fmeans ofparts (Fig. 10),. secured on the tracks 18 and fitting into sockets inthe tracks 19. I I

As a means for holding the front ends of the front tracks 19 there areshown supplemental or temporary posts or pedestals .27-

(Figs. 10 and 10) which as shown in Figs. 3 and 4, are placed at thefront or outer ends of the tracks 19. These members 27 are preferably inthe form of simple cast pedestals having their lowcrends provided withpins 28 to fit into apertures in the floor and having their upper endsprovided withscrews 29to adjust the height of the tracks 19 thereon. Thetracks 18 are provided with stops 29 for checking the back movement ofthe table and the tracks 19 are provided with stops 30 for checking theforward movement of the table. To permit the latter movement of thetable. it is provided with rear wheels 31 and front wheels 32, (Figs.3,4, 8 and 19), the rear wheels 31 being arranged to travel on thetracks 13 and the front wheels 32 to travel on the tracks 19. \Vhe'els31 and 32 are enclosed in housings at joints of table sections, Figs. 8and 10 Shafts for said wheels are mounted on opposite ends of adj aecnttable sections.

As an-arrangement for driving said wheels or certain of them, a drivingshaft 33 (Fig. 8) is mounted on the table and extended lon'- gitudinallythereof substantially from end to end of the same, as shown in Fig.1.Bearings 34, for the left hand end of said shaft 33 are shown moreclearly in Fig. 6, intermediate bearings 36 and 37 'in' Figs. 7 and- :8,respectively, and right hand end hearings in Fig. 9. The drive-shaft 33is provided with pinions 39 and the table wheels 32 are provided withrack teeth 40 meshing with the pinions 39 whereby the rotation of theshaft 33 will rotate all of the wheels 32 and thereby cause the table tobe shifted laterally-one way or another on the tracks.

18 and 19, according to the direction the shaft 33 is rotated.

As a means for rotatingthe drive shaft 33 weshow a motor 42,- (Fig. 7)which may be an electric motor mounted upon andcarmotor 42 is connectedthrough gears 43 and .44 with a drive shaft 45 which. carries a worm 4(5meshing with a worm wheel 47 (Fig. 10) on the main longitudinallyextending drive shaft 33. Thus by the operation of the motor 42 and itstrain of mechanism the drive shaft 33 may be turned in one direction oranother, and the table A shifted latcriilly. one direction or another,according to the direction of rotation of the motor. As an arrangementfor adjusting the table A to permit it to be lifted slightly to allow ofits lateral motion, we provide lifting devices which are capable oflifting the tracks 18 and 19 slightly and thereby not only adj-ust-''ing said tracks .upwardly against the table wheels 31 and 32, but alsoadjusting said tracks upwardly .to an extent to lift the .table slightlyfrom the posts. or pedestals 2, 3, 4, etc. These lifting devices whichare best shown in Figs. 7 and 10, comprise lifting screws 5()-5(), onefor .eaeh post or pedestal, a'nd cams 751, on rock shafts 52 controlledby levers 53, the lifting screws 50 being provided with socket members54 mterposed between them and the cams 51 and resting on the latter. Theupper ends of these screws 50 are provided with plates 55 which fitagainst the lower surfaces of the tracks 18 and 19 and between lugs 56and 57 thereof, so that a swinging movement of the levers 53 willeausethe screws 50 to push upwardly against the tracks 18 and 19 and "therebyliftthe same. This lifting actionis very slight bun sufficient to causethe tracks 18 and 19 to contat with the table wheels 31 and 32 and topushthc same 11pwardly to an extent to lift the tableslightly up fromthe pedestals 2, 3, 4, etc. The lift ing screws 50 may be adjusted tocertain extents so as to cause them practically to contact with thetracks 18 and 19 before the levers 53 are swung, by turning the threadedsockets 54 relatively to said screws 50.

-Thusit will be seen that the rails 18 and 19 may be put lll position,as shown in Figs.

3, 4 and 5. and then the levers 53 on the pedestals fl 3,- .4, etc...may he turned so as to lift thetahle A slightly 1111' from saidpedestals and then the motor 42 may he started, turning the wheels 31and 32 and causing the table to move on the tracks 18 and 19, direc-. i

tion of rotation of the motor being such as to cause the table tomove tothe left, (Figs.

3 and 10) so that it will move from the position shown in Fig. 3 to theposition shown in Fig. 4. f I v There are also other parts" or elementsof the machine which must be taken care of in this movement and"explanation of these will now be made, I

One of these element; i the deckel Strap 7 and its supporting wheels 8and 9. in connection withthesame the pond walls 60, Figs. 1 and (3.These parts are intended to be lifted by cranes which may engage thewheels 8 and 9 and lift the same above their normal positions, as shownin Fig Z. The pond (S0 is also lifted and the construction by which thisis accomplished will now be explained. This pond 60 which is best shownin Figs. 6, 17, and 18, is arranged at the side of the head box 61 andis secured thereto in such manner to permit the pond (30 to be raisedrelatively to the box (31, as shown in Fig. 2. To such end the front andrear walls of the pond. the front wall or plate (53 being shpwn, (Fig.17) are secured to the adjacent wall (51 of the box (51 by means ofclamps (55 (Fig. 17). One end of each clamp (Sirestsand acts upon anangle bar 66 secured by bolts (37 to the plate (33 and the other end ofeach clamp (35 contacts with and acts against a vertically extendingstrip (38 which is secured as by bolts (30 to the outer side of the tankwall (34. The clamps are held in position by bolts 70 passing throughthem and into the strips "68. 'Each clamp (35 has a slot 71 permittingit to have a certain amount of play or longitudinal movement withreference to the bolts 70, and the strips (38 are provided withdifferent apertures 72 into any one of which a bolt ;70 may be placed inorder to allow a further extend of longitudinal adjustment of the clamps05. By loosening the bolts 70 the box (51 is bodily elevated. In thisconnection it may be notedthat the forward and back adjustment of thewall or plate 63 is permitted by loosening the clamps 73 so as to permitthe sleeve 74 to slide on the cross bars or rods 75 and thereby permitthe wall (33 to be moved laterally as desired to accommodate differentwidths of paper to-he made by the machine, the position of the plate (53detern'iining the length of the slot or opening 76 (Fig. (3) throughwhichythe pulp or material from the pond is fed on to the wire.

This transverse movement of the plate (33 is accomplished by means of acrank handle 77 (Fig. '17) which turns the shaft 78 carrying a gear 79which meshes with a gear 80 on a shaft 81 which extends upwardly anddiagonally across the front of the tank, as shown in Fig. (L and has itsupper end provided with a gear 82 meshing with a. pinion 83, on a rotarysha'ltti4. 'lhe shafts TS and 84 have threaded ends 78' and 84, respectively. which engage with the-plate (33 or parts thereon, and so adjustsaid plate laterally when said rods 78 and 84 are turned by the rotationof the crank handle 77. The deekel wheel 8 is mounted'on the plate 63,as shown in Fig. 18, the axle 8 of the same having an extension 9"passing through the tits in a slot 90 by which the wheel 8 may beadjusted vertically. (Figs. (3 and 18). Thus the deckel wheel 8 willmove with the pond 60. In order that the upper cross shaft T5 may risewith the pond (30, the bearing 01 for the same is made open so that saidshaft may be lifted bodily out, of said bearing. thereby pern'iitting itand all of its connections to leave the bearing and go with the pond andassociated parts. The bearing $10 is so located as to permit the pond toswing upwardly about the shaft 75 as a pivot. The other deckel roll 9will be lifted bodily from its bearings 93(Figs. 19 and 20) by releasingsaid screws 94 which screw into the upper parts of said bearings 03, thelatter being open at their upper ends or U shaped. as best shown inFig.10. The set screws 04- hold the shafts 0 of the deckel wheels 0 inproper position in the bearings 92, until it is desired to lift thedeckel strap and associated parts, in which the screws 01- will beundone, thereby permitting the shafts 9 to be lifted out of the bearings03, and the rvheels 9 to be lifted bodily by cranes or otherwise withthe docket straps T thereon. .For longitudinal adjustment the bearings93 are shown mounted on cross heads 95 which are arranged for slidingmovement in standards 96 secured in position by screws 97, said movementbeing accomplished by rotation of a screw 98 having a hand wheel 99. Inthis way the deckel strap and its pulleys together with the pond andassociated ,lifted bodily, as shown in Fig. 2.

Arrangement is also made for adjustment of the couch rolls 15 and 16 topermit the re.- moval of the wire. To such end the upper couch roll 16is mounted on swinging frame members 100 (Figs. 1, 0 and 15). each ofwhich is adapted to swing upwardly and backwardly about a pivotalconnection"101 located'at the upper end of a base or body member 102mounted on the floor close to but separated from the endniost post orpedestal I (3. The member 100 is provided with a pro- 109 on the member102. By undoing the nut 108 the rod 104 may be released, thereby permitting the member 100 to be swung up 1 wardl'y to-the elevated 15. a Aswinging bar 110 is pivoted on the pro ection 109 at 111, and is inengagement with the nut 108. so that said pivoted bar 110 will exertdownward pressure on the rod 104,

parts, may be position shown in Fig.

with a projection 120 subject to pressure of toreceive said dowel pins.The block 123 on tending to hold the roll 16 downwardly on the wire B. Aweight 112 is mounted on the bar and arranged to slide on the same so asto adjust the pressure exerted by the rod 10-1. -The couch roll 16 isprovided with a scraper blade 113 mounted on a block 114 which isadjustable by means of a screw 115 having a wheel 116 and a stop nut117. The board 114 is mounted on an adjustable member 118 pivoted at115) on, the end of the .member 101) and said member 118 is provided aspring 121. which surrounds a rod 122 an 1 is subject to the adjustmentof a rotary nut 123, whereby pressure may be exerted on the scrapingblade 113. The rod 122 is pivoted at 124 and a smaller and weaker spring125 is located between the pivot 124 and the member 120 so as to liftthe member 120 when the pressure of spring 121 is reduced or released. IThis blade 113 with all its associated mechanism -1S lifted bodily andswung upwardly when the member 100 is swung lip-- wardly to lift thecouch roll 16. The lower the front side of the machine.-that is the.nearest side looking at the machine as in Fig. 1, is pivotally mountedby meansof a pivot screw 131, whereby said block 123 may be swung aboutsaid pivot to the right rel'erring to Fig. 9. sothat it will come intoposition at the right haudside of its usual position, as shown in Fig.15. In this way said block 123 may bemoved out of the way of the wire llso as to permit the latter to he slipped on or oil from the roll 15. Theother or rear beariug 127 for said roll '15 is per manently secured toits block 128', Fig. 16), and the latter is secured to the base. member1H2. as by s-rews 132; 'lheupper-part 127' ofthe back bearing 127.however is simply pulled down, so that it may be removed and permit therear end-of the axle 15' .of the couch roll 15 tobelifted out of saidbearing 127." In this waytheuppercouch roll 16 may be swung upwardly andbachwardly entirely out of the way and the lower couch roll 15 may havethe wire pulled over it and may be lifted bodily upwardly and to theleft. so as to give the wire slack, as shown in Fig. 15.

Another the wire tightener 135, best shown inFigs.

1, 8, 21, 22 and 23. This wire tightener comelement to receive attentionis prises a roll 136 adapted to rest upon the wire 2 and tighten thesame. The roll 136 is mounted in bearings 137,1which are secured to andsuspended from sleeves 138 and mounted on vertically arranged adjustingscrews 140. These screws 140 are provided at their upper ends with.mite-r gears 141 which mesh with pinions 142 mounted on the oppositeends of a rotary shaft 143 (Fig. 21). A hand wheel 144 controls theshaft 143 so that by turning the hand wheel 144 the pinions 142 willturn the screws 140 and there by cause the sleeves 138 to be raised andlowered so as to raise and lower the roll 136 and thereby vary thepressure applied by said roll to the wire B. The hand wheel 144' isatthe front end of the shaft 143, as shown in Figs. 8 and 21.

Arrangement is made so that this tightening device may be swung to'oneside, preferably upwardly and to the left, referring to Fig. 8, so as tolift the roll 136clear of'the wire B, and alsoso that the screw 140maybe out of the way to permit movement of the table relatively .to thewire. In the arrangement shown,,the shaft 143 serves as apivotalmounting for the screws 140 and associated parts, and totemporarily hold the wholea-rrangement in position. A clamp orconnection 147 is shown between the lower end of the bracket or frame148 and the side 5 of the'post or pedestal 5, said bracket 147 beingsecured to the flange 51 by bolts 149 and to the standard or upright 148by bolts 150. To

the bearing 151 bolted to the lower end of the frame 148 and serving asa support and bearing for the lower end of the screw 140, isattacheda-rope or flexible connector 152 which extends upwardly andaround a rotary shaft 153 suspended by abearing 154 from the table A,whereby by the rotation of said shaft v153 the flexible connector 152may be wound on the shaft 153. and the tightening device 135 may beswung upwardly and to the left, referring to Fig. 8. The shaft 153 maybeturned to accomplish this by means. of a hand wheel 156. A cog orratchet arrangement is provided consisting of a cog wheel 157 and apivoted dog 158 by engaging the cogs on wheel 157 and thereby holdingsaid shaft 153 in any adjusted position. By this arrangement thetighteningdevice as a whole may be swung upwardly and to the left andheld in said elevated position, practically horizontal if desired.

Onthe table A there is another roll 160 mouute dfat its right hand endonthe bracket 161, as shown in Fig. 9. This roll supports the wire 2 andbeing mounted on the tab e A."moves with it. Another roll 162 isarranged below the roll 160 and mounted on a bracket 163 on the endmostpost or'i'pedestal 6 as shown in said Fig. 9. .This 17011162 be ngmounted on the pedestit1'6,fdoes not I move' with the tableA when thelatter is shifted laterally. but remains on the pedestal, as shown inFig. 2. .\nothcr roll 16?). (Figs. 1, 2 and T) is shown mounted on thepedestal 4 and this also supports the lower stretch or reach of the wire1 but does not move with the table. being on a edestal. ()ther pedestals166. N37. and 16s are shown (l ig, 1) and these pedestals arerespectively provided with rolls 169. 170 and 171. also serving tosupport the under stretch or reach of the wire Ii.

Thus it will be seen that by the use of the tracks 18 and 19 andthe.supplemental track supporting pedestals 24'. and by operating themotor 52 so as to rotate the main driving shaft 33, the table may bemoved forwardly on to the tracks 19. as shown in Fig. r. the

entire table from one end to the other moving forward in this manner and'arrying with it the breast roll 14, the table rolls 10 and the end roll161). but not taking with it the dcckel strap 7 and associated parts,nor the couch rolls l5 and 16, which as previously explained are capableof independent adjustment to permit the movement of the table withouttheir following. Before the table is thus advanced to its forwardposition, the deckel straps 7, with the deckel wheels 8 and 5), and thepond (it) are lifted bodily as previously explained so that they allclear the table and its wire, as shown in Fig. 2. Also the couch roll 16is swung up and back and the other couch roll 15 lifted by cranes, asshown in Fig. 2. \Vhen the machine is arranged in this way the tracksare put in place, the table with all its attached parts run out on thefront tracks as in Fig. 1, and a new wire is put its place.

To put the new wire in place, it is first slipped on the bottom couch inthe usual way, and raised to." position 15, (Fig. 2). Pipes are shown inFig. 2, as 175, 176, 177, 178, 179 and 180, all of these pipes beingtemporarily held in position at the sides of the pedestals 2, 3, 4, I),and (3, by means of holding devices such as shown in Figs. 11 and 12.Thoma comprise sad'ics 1H1 bolted to the various pedestals by bolts 182and having seats 18% to receive the pipes, and pins 184 arranged to passthrough side arms or projections 15%;) and attach to the saddles 181 bymeans of chain 1%. These pipes are placed over the lower reach orstretch of the new wire which iSStIllIig over the rolls 169, 170, 1th),171 and 162, said rolls supporting the wire and said pipes holding itdown, and also over pipes 188 and 189, supported by a rod 190 held inplace by bracket 191 at the left hand end of the machine, as shown inFig. The portion of the new wire between the pipe 188 and the couch roll15 is supported by cranes or other lifts indicated diagrammatically at Iextg'udmg longitudinally of the table and 192, 193, 194 and 195. Whenthe new wire is thus suspended and arranged, as shown in Fig. 2, it isin condition to allow the table to be moved back in place. It is thenlowered so that it will rest on the-table rolls 1, and will encircle thebreast roll 14: and being al' ready extended around the couch roll 15.the, latter is lowered into its bearings which have lirst been properladjusted for it and then the pipes 175, 176, etc., are removed.permitting the lower stretch of wire to rise. The table with the wire onit to this extent is then moved baclovardly by operating the motor 42 ina reverse direction. and more or less at the same time the couch roll 15is lowered. thereby permitting the wire to come into its proper positionwith the slack taken up and the couch roll 15 adjusted back to itsnormal position and the couch roll' 16 lowered so as to apply tension tothe upper stretch. The tightening device 135 is then lowered so as toapply tension to the lower stretch. The deckel straps T with theirassociated parts are then lowered into position and other adjustmentsmade so that the table is back in its place carrying a new wire and themachine is all ready for operation \Vjtll that new wire. The tracks 18and 111 are then removed and the operation is completed. and themachinev ready for further use.
